Question

Diagramatically show the difference between parenchyma, callenchyma

and sclemenchyma on the basis of cell wall

Answer

Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin.

Key Differences Between Parenchyma, Collenchyma and Sclerenchyma

➠Given below points will differentiate the three types of ground tissues present in plants, which are parenchyma, collenchyma and sclerenchyma:

• Parenchyma is one of the types of living plant cells originating from ground and protoderm meristem. These type of cells are most abundantly found in plants tissue. Another type of living plant cells originating from the pro-cambium, known as collenchyma cells. The epidermal layers of the plant are made of these cells. Thirdly the hard and outer part of the stem is made up of the sclerenchyma cells. These are the dead plant cells which originate from ground meristem and protoderm procambium.
• Parenchyma cells are found in every soft part of the plant, but collenchyma cells are found in specific part of the plant like leaves, stems, and petioles, whereas sclerenchyma cells are found in mature parts of the plants or trees.
• There are different types of shapes of all the cells, but generally, parenchyma cells are isodiametric, while collenchyma are elongated and sclerenchyma are sclereids, fibre in their shapes respectively.
• Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin.
• Intercellular space between the cells is present in parenchyma cells, while in collenchyma cells less space is present between the cells and in sclerenchyma cells, intercellular space is absent due to which cells are tightly packed.
• The function of parenchyma cells is in the storage of foods, in gaseous exchange, and in photosynthesis, while collenchyma cells provide mechanical support and elasticity to the plant, the sclerenchyma cells provides mechanical support to the plant. It also supports transportation of water and nutrients to the plants.
